Description

Technical Field

[0001] This utility model relates to the field of lathe loading and unloading technology, and in particular to a waste cleaning device for a lathe used for machining external threads of galvanized pipes. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, cylindrical and conical threads, etc. of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other operations. Before machining, the workpiece needs to be fixed in the workpiece chuck of the lathe.

[0003] Taking the machining of external threads on galvanized pipes on a CNC lathe as an example, a large amount of waste is generated during the machining process. The waste falls into the loading and unloading tray below. The existing methods for handling the waste involve manually brushing it together with a small brush or removing the loading and unloading tray from the lathe. Moreover, the existing loading and unloading devices cannot be adapted to the processing of galvanized pipes of different diameters, resulting in uneven accumulation of waste, poor unloading effect, and high labor intensity for workers. Utility Model Content

[0004] To address the aforementioned technical problems, a waste removal device for lathes used in machining external threads of galvanized pipes is provided. The technical means employed in this invention are as follows:

[0005] A waste cleaning device for a lathe used for machining external threads of galvanized pipes includes two fixed seats (left and right) and a first mounting shaft and a second mounting shaft mounted on the fixed seats. There are two first mounting shafts, each positioned above the second mounting shaft. The two first mounting shafts are fixedly mounted to corresponding loading / unloading trays. Each fixed seat has a through hole for the first mounting shafts to pass through. The second mounting shaft is fixedly mounted inside the two fixed seats.

[0006] The loading and unloading trays have openings at the top for receiving waste materials. The bottom of each of the two loading and unloading trays has a mounting groove on one side facing each other to accommodate an extension plate. The bottom of the two loading and unloading trays is provided with a movable plate and a movable mechanism. The movable plate is connected to a sleeve that is fitted onto a second mounting shaft. The bottom of the sleeve is provided with a fixing mechanism. The movable mechanism is used to adjust the distance between the two loading and unloading trays. In the confirmed working state, the relative positions of the movable plate and the second mounting shaft are fixed by the fixing mechanism.

[0007] Furthermore, the second mounting shaft has slots at preset intervals for the insertion of a fixing mechanism.

[0008] Furthermore, the fixing mechanism includes a housing and a T-shaped snap-fit ​​rod mounted on the housing. The T-shaped snap-fit ​​rod includes a handle and a rod. The handle and the rod are arranged perpendicularly to form a T-shape. After the rod passes through the housing, its head can contact the second mounting shaft. A hole is provided at the center of the bottom of the sleeve for the head of the T-shaped snap-fit ​​rod to pass through. A partition is fixedly installed at a preset position on the rod. A spring is provided between the partition and the housing on the side near the handle.

[0009] Furthermore, the moving mechanism includes a connecting plate and a first threaded rod. There are two connecting plates, which are respectively installed at the bottom preset positions of the two loading and unloading trays. Both connecting rods are threadedly connected to the first threaded rod. The first threaded rod is provided with threads in opposite directions corresponding to the positions of the two connecting plates.

[0010] Furthermore, a horizontal plate is installed on the upper part of the two fixed seats. The horizontal plate serves as a mounting plate for the cleaning mechanism, which includes a cleaning unit and a lateral moving device for the horizontal movement of the cleaning unit.

[0011] Furthermore, the lateral movement device includes a servo motor, a second threaded rod, and a connector mounted on the horizontal plate. The output end of the servo motor is connected to the second threaded rod, and the end of the second threaded rod is connected to the horizontal plate. A rolling bearing is provided between the two. The connector is threaded, and a cleaning unit is installed at the bottom of the connector.

[0012] Furthermore, the cleaning unit includes an electric push rod and a blowing mechanism installed at the bottom of the electric push rod. The blowing mechanism includes a blowing housing and a fan installed on the blowing housing. One end of the fan is connected to a compressed air source through an air supply pipe, and the other end of the fan extends into the blowing housing. Multiple nozzles are provided at the bottom of the blowing housing.

[0013] This utility model has the following advantages:

[0014] This invention provides a waste material cleaning device for lathes used in the machining of external threads on galvanized pipes. It allows for adjustment of the waste material receiving area of ​​the loading and unloading trays according to different pipe diameters, facilitating cleaning of the trays. By setting an mounting shaft, when loading or unloading larger workpieces, pulling the T-shaped locking rod disengages it from the second mounting shaft. The two loading and unloading trays then move apart, causing the extension plate to slide out. Finally, the T-shaped locking rod engages with the slotted part of the second mounting shaft, increasing the area of ​​the loading and unloading trays and facilitating adjustment for waste materials of different pipe diameters. By incorporating a cleaning unit, when cleaning the loading and unloading trays is required, a second servo motor drives the second threaded rod to rotate, which in turn drives the cleaning unit to clean the inside of the trays. A blower further cleans the inside of the trays, improving the cleaning effect and greatly enhancing its practicality and ease of use for operators. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 , Figure 2 As shown in the figure, this utility model discloses a waste cleaning device for a lathe used for machining external threads of galvanized pipes. It includes two fixed seats 1 (left and right) and a first mounting shaft 24 and a second mounting shaft 4 mounted on the fixed seats. There are two first mounting shafts, each positioned above the second mounting shaft. The two first mounting shafts are fixedly mounted to corresponding loading / unloading trays 5. Each fixed seat has a through hole for the first mounting shafts to pass through. The second mounting shaft is fixedly mounted inside the two fixed seats.

[0021] The loading and unloading trays have openings at the top for receiving waste materials. The bottom of each of the two loading and unloading trays has a mounting groove 23 on one side facing each other to accommodate the extension plate 8. The bottom of the two loading and unloading trays is provided with a moving plate 6 and a moving mechanism. The moving plate is connected to a sleeve that is fitted onto the second mounting shaft. The bottom of the sleeve is provided with a fixing mechanism. The moving mechanism is used to adjust the distance between the two loading and unloading trays. In the confirmed working state, the relative positions of the moving plate and the second mounting shaft are fixed by the fixing mechanism.

[0022] As an optional implementation, both mounting bases are fixedly connected to a shock-absorbing pad at their bottom, the shock-absorbing pad having a thickness of not less than three millimeters.

[0023] As an optional implementation, the interior of the loading and unloading tray can be provided with a slope section that gradually decreases from the inside to the outside to facilitate the collection of waste.

[0024] The extension plate 8 will have a certain frictional force during the left and right movement of the two loading and unloading trays. Therefore, as an expandable implementation, several rollers can be set at the bottom of the extension plate to replace sliding friction with rolling friction, so that the workers can easily separate the two loading and unloading trays.

[0025] Of course, the space that the loading and unloading trays can move between needs to be limited. Specifically, the length can be designed according to the actual working scenario to prevent the extension plate from falling between the loading and unloading trays at the limit position during operation.

[0026] Since the first mounting shaft will be in direct contact with the through hole of the fixed seat, there will be a certain amount of friction when it moves. Therefore, before actual movement, a certain amount of grease can be applied to the bottom of the first mounting shaft to reduce friction and facilitate the movement of the first mounting shaft.

[0027] This device is positioned below the machine tool, specifically above the fixed base and crossbeam. After the machine tool completes the external threading of the galvanized pipe, waste material is generated, which is collected by this device. The machine tool mentioned in this embodiment can be a traditional machine tool or a CNC machine tool. Of course, for some machine tools that can be modified, this embodiment is applicable not only to the application scenario of external threading of galvanized pipes but also to other work scenarios where waste recycling efficiency is relatively low.

[0028] Furthermore, the second mounting shaft has slots at preset intervals for the insertion of a fixing mechanism.

[0029] Furthermore, the fixing mechanism includes a housing and a T-shaped locking rod 20 mounted on the housing. The T-shaped locking rod includes a handle and a rod, with the handle and rod arranged perpendicularly to form a T-shape. After the rod passes through the housing, its head can contact the second mounting shaft, specifically the "groove for insertion of the fixing mechanism" mentioned above. A hole is provided at the center of the bottom of the sleeve for the head of the T-shaped locking rod to pass through. A partition 21 is fixedly installed at a preset position on the rod, and a spring 22 is provided between the side of the partition near the handle and the housing.

[0030] The housing is a covering structure formed by the four sides and the bottom (near the handle), forming a mounting cavity 19. Its top surface can be the bottom surface of the sleeve or an additional top panel. If the former is provided, the bottom surface of the sleeve is directly connected to the four sides. If the latter is provided, the top panel fits the sleeve, and the curvature of the top panel is adapted to the sleeve. Furthermore, a hole of the same specification as the hole at the center of the bottom of the sleeve is opened on the top panel.

[0031] In one optional implementation, the moving mechanism includes two connecting plates 7 and two first threaded rods 9. The connecting plates are respectively installed at preset positions on the bottom of two loading / unloading trays. Both connecting rods are threaded onto the first threaded rod, which has threads with opposite helical directions corresponding to the positions of the two connecting plates. One end of the first threaded rod is equipped with a driving device, such as a motor or a manually operated rocker arm.

[0032] As another alternative implementation, the moving mechanism can be a handle that is horizontally or vertically mounted on the side of the loading and unloading tray, which can help the operator to move the loading and unloading tray after the T-shaped locking rod is disengaged from the second mounting shaft by gripping the handle.

[0033] Furthermore, a horizontal plate 10 is installed on the upper part of the two fixed seats. The horizontal plate serves as the mounting plate for the cleaning mechanism, which includes a cleaning unit and a lateral moving device for the horizontal movement of the cleaning unit.

[0034] Furthermore, the lateral movement device includes a servo motor 11, a second threaded rod 12, and a connector 13 disposed on the horizontal plate. The output end of the servo motor is connected to the second threaded rod, the end of the second threaded rod is connected to the horizontal plate, and a rolling bearing is disposed between the two. The connector is provided with threads, and a cleaning unit is installed at the bottom of the connector.

[0035] The lateral movement device can also directly use existing linear modules, in which case it needs to be integrated into the horizontal plate.

[0036] Furthermore, the cleaning unit includes an electric push rod 14 and a blowing mechanism installed at the bottom of the electric push rod. The blowing mechanism includes a blowing housing 15 and a fan 16 installed on the blowing housing. One end of the fan is connected to a compressed air source 17 through an air supply pipe, and the other end of the fan extends into the blowing housing. Multiple nozzles are provided at the bottom of the blowing housing. The compressed air source can be directly from the factory's compressed air storage tank. Depending on the actual site requirements, a ventilation plate 18 can be installed inside the blowing housing to facilitate uniform airflow. Alternatively, a filter screen or other device can be installed inside the blowing housing to prevent dusty debris blown back into the blowing housing.

[0037] In other expandable embodiments, brush heads, bristles, or other structures can be added to the bottom of the purging housing to achieve cleaning within a certain range of the loading and unloading tray.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
